Abstract

The broken and priceless of papaya in the market potentially modified as Nata called nata de papaya with the help of Acetobacter xylinum. During the fermentation, acid condition were needed by bacteria to growth and developement. Acetid acid glasial 99,8% were needed to make acid condition. The use of Averrhoa bilimbi as the subtitutan of glacial acetid acid were predicted can reduce the effect of chemical substance in food. The aim of this study to 1) know the effect of adding averrhoa bilimbi water toward the quality of nata de papaya, and 2) determined the exactly level of the averrhoa bilimbi extract toward the quality of nata de papaya. This research use Complitely Randomized Design (CRD) using 3 treatment of adding averrhoa bilimbi extract (2 ml, 5 ml, 8 ml) and 6 replicant. The data were collected by the observation by using measurement tools and organoleptic test by presenting 10 panelis. Data were analized by using Kruskal Wallis Analisis. Based on the result, could be known that there is no relation of treatment by adding averhoa bilimbi toward quality of nata de papaya. which is shown that averhoa bilimbi could subtitute the role of glacial acetid acid in the process of making nata de papaya.

Abstract

This study aimed to inform the public about the potential utilization of rubber wastewater and disposable diaper waste as raw materials for organic fertilizer using Pumakkal as a fermentor to enhance edamame productivity. The method used was a literature study of relevant scientific sources, including national and international journals, books, and research reports discussing the characteristics of rubber wastewater, the hydrogel content and organic compounds in disposable diapers, the role of indigenous bacteria in Pumakkal during the fermentation process, and the compliance of organic fertilizer with Indonesian National Standard (SNI). The results showed that rubber wastewater still contains organic materials with potential use as fertilizer, while disposable diapers contain hydrogel and organic compounds from urine that can support nutrient availability. Pumakkal fermentor, which contains indigenous bacteria derived from pineapple wastewater, was able to effectively degrade organic materials, resulting in fertilizer that meets SNI quality standards and has the potential to be applied to improve edamame productivity. In conclusion, the utilization of rubber wastewater and disposable diapers with Pumakkal fermentor shows promising potential as an environmentally friendly organic fertilizer and as a sustainable solution for waste management and edamame productivity enhancement.
